Application tiled May 23. 191e. Serial No. 840,499.

T0 all ulwm it may concern lie it known that l, ERNEST H. GAGNON, a citizen of the United States, and a resident of Billings, in the county of Yellowstone and State of Montana, have invented a new and Improved Smoke Filter and Sparklliminator, of which the following is a full, clear and exact description.

This invention relates to improvements in devices for filtering smoke and eliminatingsparks from locomotives and the like, and has for an object to provide an improved structure which will filter and clean smoke from a locomotive previous to its discharge without affecting the usual draft pro vided.

Another object of the invention is to provide a device which may be connected with the usual smoke stack of an engine for re,- ceiving the smoke therefrom and washing the smoke before dischargin the same.

A still further object of t e invention is to provide a washing device for the smoke from a locomotive or other similar device which will force the smoke through a given quantity of water, and willcmix thesmoke with the water so as to properly clean thesmoke and cause the solid particles to precipitate, whereby the solid particles of the smoke may be discharged at predetermined intervals and the gaseous part allowed to pass out a suitable diharge pipe.

lin carrying out the objects of the invention the same may be applied to any/kind of engine, as for instance a locomotive engine of any desired type. When applying the device to a locomotive a cap is provided for the smoke stack of the locomotive which is preferably hinged in place and provided with an operating member whereby the engineer may at any time move the cap olf of..

the smoke stack or allow the cap to move back on the smoke stack. Also connected with the smoke stack are a pair of tubes which merge into a single tube on top of the cab, which tube is connected with a power fan arranged upon an extra or an additional tender. rihe extra tender is prefer-` ably arranged in the rear of the usual tender connected with the engine, and is formed with a tank at the bottom portion which is designed to contain a predetermined amount of water. An outlet is provided for the tank at the bottom, and also an outlet is provided for the tank at the top, the outlet at the bottoni being for the heavy matter of the smoke, and the outlet at the top being for the cleaned smoke and gases. ln order. that the smoke and gases may be mixed with the water and thereby cleaned a power fan draws the smoke from the tube connected with the smoke stack and forces the same into a rotating stirring member which is substantially the shape of a blow fan. This stirring member has the blades extending into the water in the tank and thereby forces the smoke in small quantities into the water and at the same time stirs the Water so that there will be an intermixing of the smoke and Water and thereby the smoke will be cleaned of all the heavy matter therein.

lln the accompanying drawings-Figure 1 is a side view of an engine and an embodiment of the invention applied thereto; Fig. 2 is a top plan View of the structure shown in Fig. l; Fig. 3 is a section through Fig. 5 approximately on line 3 3; Fig. 4 is an end vlew of a tender embodying certain features of the invention, the same being taken approximatel on line 4-4 of Fig. 3; Fig. 5 is a section t rough Fig. 3 approximately on line 5-5.

Referring to the accompanying drawings by numeral, l indicates an engine of any de-V sired kind and 2 the usual tender. Connected with tender 2 is a second tender 3 of lspecial construction to whiclrthe train may be secured in the usual manner. The engine 1 is provided with the usual smoke stack .e to Whichis pivotally connected a cap 5, the pivotal connection heilig preferably provided with a spring so as to normally hold the cap closed. A cord, rod or other suitable means 6 is also provided whereby the engineer mayopen the smoke stack 4f by pulling upon the cord and may hold the same open upon fastenin the end of the cord in the cab inany desire manner. During the operation of the present invention cap 5 is maintained closed so that the smoke may pass into the pipes 7 \and 8. Pipes 7 and 8 straddle the usual steam dome') and also any other attachments on the engine. rlhe pipes 7 and 8 merge into or are connected with a single pipe 10 which slidingly fits into a suitable support 11 arranged on tender 2. Connected v with pipe 10 is a exible pipe l2 which slidingly fitsI into a support 13 and is coupled lto a flexible pipe 14 extending into/the tender 3. Pipes 7, 8 and 10 may be made of any1:

AHl

suitable material but preferably of some l ably in pipe 29 for controlling the flow of good quality of metal, while pipes 11 and 14 are flexible and may be made of any suitable material which will be flexible and withstand the heat of the smoke passing therethrough. Iipe 14 extends into the upper part of the tender 3 (which is formed on the order of a eab as shown in F ig. 3), and is connected to the eye of a blow fan 15 (Fig. 5). The blow fan 15 may be of any desired structure' and may be operated from any desired power means, as for instance the motor 16. As the fan l5 operates the smoke is drawn through the pipes heretofore mentioned and forced through a passageway 17 into the housing 1S.

Rotatably mounted in housing 18 is a fan or paddle wheel structure 19 which receives the smoke and causes the same to be moved downwardly into the Water 2O in the tank 21. The fan or wheel 19 may be driven b v any desired ower, but preferably is driven by the smo ie forced against the same b v fan 15. As the wheel 19 rotates the same stirs up the water and creates a heavy vapor in the space 22, whereby the smoke is not only brought in contact with the water as the same passes over wheel 19 but must pass through this heavy spray or vapor before it can reach chamber A discharge pipe Z-l is connected with chamber 23 so as to discharge. the cleaned smoke and gases from the tender. Housing 18 in which wheel 194 is arranged forms part of the tank 21, which tank is provided with an inclined bottom 25' which has an outlet Q6 arranged at its lower` `v most point. The outlet 26 may have a cap or valve arranged therein of any desired kind without departing from the spirit 0f,

the invention so as to present means which will allow a ready cleaning of the tank. A rranged at a convenient point in tank 21 is an overliow pipe Q7 which has the upper. end protected by a suitable overlapping shield 28, whereby a slight agitation of the water in tank 21 will not causeany overflowing thereof. e

In operation when it is vdesired to use the device all that is necessary is to start motor 16 and then close cap 5. This will cause all the smoke and foreign products of combustion passing through smoke stack 4 to be cleaned by being brought'into contact with the water Q0 in tank 21. This eliminates the discharge of smoke having soot therein or other objectionable'matter so watcr from tender 2 to tank 21.

lVhat I claim is- 1. In a device for filtering smoke and eliminating sparks from locomotives, a fan for drawing smoke from said locomotive and dischargin the same to a given point, a tank provided with a given quantity of water, an agitator arranged in said tank, means for guiding the smoke discharged from said fan to said agitator for operating the agitator and for mixing said smoke with the water in said tank, and means for directing the cleaned smoke to a discharge point.

2. In a device for filtering smoke from a locomotive, a blow fan for sucking the smoke from said locomotive, means for directing the smoke from said blow fan, a paddle wheel arranged in the path of movement of said smoke and rotated thereby as the same `'is directed from said fan,` a tank provided with a given supply of water, said water partially submerging said paddle wheel, whereby the water 'and smoke are mixed, means forming a settling chamber for the smoke, said means merging into said tank, and means for directing the cleaned smoke to a discharge point.

3. -In a device for filtering smoke from a. locomotive, a. tank ada ted to contain a quantity of water, a rotating agitating member projecting into said water, and a fan for drawing smoke from said locomotive and discharging the same againstv said agitating member for causing the agitatin v member to rotate and mix the smoke an water, and means for directing the cleaned smoke to a discharge point.

4. In a device for filtering smoke and eliminating sparks from locomotives, av

suction fan for sucking the smoke from said locomotive, a discharge tube for discharging the smoke from said suction fan, a tank adapted to contain Water, an-agitating member with some of the blades continually in contact with said water, a housing for said agitator, said housing being opened at one side to said tank, and at the other side vto said discharge tube, said discharge tube being arranged so as to'discharge the smoke at av tangentto the blades of said agitator whereby said agitator is rotated and thereby agitates the water and mixes the smoke therewith. and means associated with the tank for discharging the filtered smoke.

In testimony whereof' I have signed my. name to this specification in the presence of two subscribing witnesses.
